Yes and adjust the needle down. Sometimes can run up to a 110 main.
YES YOU DO. JUST LEAN THE NEEDLE DOWN ONE KNOCH, CLEAN YOUT PLUG OR CHANGE TO A NEW ONE AND RUN THE SHIT OUT OF IT FOR A BRIEF TIME, TURN OFF AND CHECK THE PLUG, IT SHOULD BE A NICE TAN TO DARK BROWN. IF IT'S STILL BLACK AND OILY GO DOWN ANOTHER KNOCH. YOU WILL KNOW IF IT'S RUNNING RIGHT RIGHT AWAY
the needle is already down all the way.. so should i jump down to an 86 or something?
is it bogging or four stroking? before down jetting, try upjetting for kicks. maybe a 100, 110. better safe then sorry.
